Can I use special characters in the SIM card name?

Stick to letters and numbers. The field allows up to ten characters, so special symbols usually just eat into that limit without adding clarity.

Will the new name carry over if I move the SIM to another phone?

No. The name is stored on your Oppo phone under SIM card & mobile data, not on the SIM itself. A different device will show the default SIM1 or SIM2 label again.

Why does my phone still use the wrong SIM for calls after renaming it?

Renaming only changes the label. Check the default SIM for calls, texts, and mobile data under the same SIM card & mobile data menu to control which card handles what.

Oppo: Change SIM Card Name

On Oppo phones with dual SIM, both cards show up as SIM1 and SIM2 in call logs, texts, and network settings. That makes it tricky to tell a work line apart from a personal number at a glance. You can swap in a custom label for each SIM instead, up to ten characters long.

Change SIM Card Name auf Oppo

Oppo phones with dual SIM slots label both cards SIM1 and SIM2 by default. That label lives in the SIM & mobile data settings inside ColorOS and has nothing to do with the actual carrier name printed on the SIM.

To rename a card, open Settings ➔ SIM card & mobile data ➔ pick the SIM card you want to edit ➔ SIM card name. Enter the new label and confirm with Save. The name can be up to ten characters long, so short labels like Work or Personal fit best.

The new name shows up in the dialer, contacts, and the status bar wherever the system indicates which SIM handles a call or data session. It does not change the number stored on the SIM, the carrier network, or any settings tied to an eSIM profile.

If calls or texts keep going out on the wrong SIM even after renaming, check the default SIM settings for calls, messages, and mobile data separately. Renaming only changes the label, not the routing behind it.

Frequently asked questions

No. The label only changes what shows up in the dialer, contacts, and status bar. Your carrier number and plan stay exactly the same.
